Farmer's Hat

The farmer's hat is a Korean go term adapted into English. It is a bad shape, named by analogy is to the cone-shaped straw hat worn by medieval Japanese warriors and later farmers. It is essentially an empty triangle with an extra stone added to form a second empty triangle, and bad for the same reasons that the empty triangle is bad.

White's shape after is called jingasa in Japanese, which corresponds to the Korean term (See here and here). However, jingasa is also defined as having twoempty triangles (see here , here, and The Go Player's Almanac), which this shape does not, so there is some uncertainty about whether this example is correct usage.
